Answer 2

Answer : The chemical symbol for the atom is Cu.

Explanation :

Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

The atomic mass of lead (Pb) = 207.2 amu

The atomic mass of iron (Fe) = 55.9 amu

The atomic mass of europium (Eu) = 151.9 amu

The atomic mass of copper (Cu) = 63.5 amu

From this we conclude that the chemical symbol for the atom that has an average atomic mass of about 63.5 amu is copper (Cu).

Hence, the chemical symbol for the atom is Cu.
